In this demo, I show you how you can set the left or right AirPod to perform a different action including Siri, Play/Pause, Next Track, Previous Track, and off.

As I mention in the demo, I'm not sure when this update became available, but the software version that this demo is based on is 3.7.2 which you can check when the AirPods are connected in Settings, General, About, AirPods.
